7s 24v 2ah Battery Module
This is actually an amazing deal however these modules will need a little work. You get 7 cells for $2.50
Here's the scoop... slobs removed these batteries with complete disregard to reuse because... well... they're slobs. Many of these modules have the balance leads cut because they just ripped them out of the hoverboards. Also most packs are discharged to around 1v per cell or lower. We took the time to balance charge 10 modules and they all charged right up and tested great. So at the very least you can salvage the cells, cycle them a few times, you'll be happy with the quality. Or if you have a balance charger you can charge up each pack fully then connect these in parallel for nice 24v modules or in series for 14s 48v modules.
So to recap, 99% of these cells will test fine when you cycle them, we can't guarantee how long the balance leads will be, and most cells will be low voltage. If you take the time to balance charge the modules and reuse the nickel and 7s configuration you will be able to build a nice pack and get excellent value out of these.
The cells are Sony US18650VC3
